An Earth-like planet with a mild climate and reliable seasons. The planet's landmasses are situated in the temperate zones, featuring open and rolling landscapes with little variation in altitude. High winds sweep across the plains and across the cold brackish seas. There are few inland waterways, and the shorelines consist mostly of rocky bluffs.

A planet covered with vast, deep oceans. A large axial tilt and a highly elliptical orbit make for extremes of temperature, driving a highly unpredictable and notoriously unpleasant weather system. The planet's only major landmass, a small continent in the northern hemisphere, features rocky terrain and several active volcanoes. No indigenous lifeforms exist here, and the only human habitation is centered around small-scale mining operations.

A lush jungle planet slightly larger than Earth. The planet rotates very slowly on its axis, causing long hot days and cold nights. A relatively small axial tilt makes for a stable, predictable climate.

A small rocky planet with a nearly toxic atmosphere of 41% carbon dioxide, 52% oxygen, and 7% nitrogen. The planet is famed for the many terraces that look as though they have been 'carved' into rock faces. An extensive network of caves also exists. While many people insist that these structures are not natural and must have been made by intelligent lifeforms, there is no actual evidence of this. In fact there is no evidence of life ever having existed on the planet besides these strange rock formations. When a nearby inhabited planet suffered a catastrophe, the caves served as an emergency refugee camp. Some of the survivors still live there today.

Homeworld of the Nixu. The Nixu are a hierarchical clan-based society, and they live in highly structured communities. Instead of cities, they build large pyramidal structures, several thousand of which litter the surface of their world. Despite their penchant for mega-structures, the Nixu make every effort to ensure that the ecological balance of their world is not disturbed, and much of the planet remains an untouched wilderness.

A small lifeless rock with an extremely thin nitrogen atmosphere. Its surface is pitted with large impact craters. No indigenous lifeforms exist here, and the only human habitation is centered around a large-scale mining operation.

Homeworld of the Gontharians: a race of color-blind reptiles with folds of skin connecting their limbs to their bodies, allowing them to glide. They prefer not to leave their home-world and use holographic representations of themselves to explore the galaxy instead.
